Here is what I have read about varying speed during break-in.

Accelerating produces pressure to dry cylinder walls a some, causing friction to wear rings and cylinder walls a bit

Decelerating causes a bit of vacuum to bring oil up the cylinder walls to lubricate and cool them and the rings.

Did the shop give you any advice? They should.

In Europe it is customary to sport an - En Rodage - sticker in the rear window to let followers know that you are not going slow or doing other odd things during your break-in just to irritate them!
